Yes, apache commons was indeed a good place to look. Thanks Susan. Being new to java, I had no idea that resource was there. Happy season all. --le ----- Original Message ----- From: "John J.

It appears really robust. We might even be able to call it to use MathType. Ss I understand it, the jar file has to be compiled for each platform. Once this is done it will go in the lib subdirectory along with the platform's swt.jar Of course, the word processor will call liblouisutdml with the bindings that we already have. This is much faster and more flexible than calling file2brl. Thanks to Laura for suggesting this apporoach and to Susan for finding the Ajpache Commons exec package. John -- John J.
